Weather Summary for Iowa
National Weather Service Des Moines IA
330 AM CDT Fri Apr 19 2024

Today: 

Quiet conditions this morning as a large area of high pressure 
descends across the region. Winds have been generally on the light 
side, but vary at least a bit with winds out of the west/southwest 
over most of the state, while southern Iowa sees northwest winds. 
Skies were largely clear, outside of some clouds passing across the
far south. Radar returns this morning are showing rain, though this
does not look to be reaching the ground, and is not expected to do so.
Frost/Freeze headlines remain across the state as temperatures sit in
the low 30s north and in to the upper 30s south, though as warming 
occurs later this morning, these headlines will drop off for the day.

Generally quiet conditions are expected today, with partly to mostly
sunny skies and temperatures warming into the upper 40s to low 50s
north and in the upper 50s across the rest of the state. Winds are
expected to turn more northwesterly across Iowa as a front passes
though, turning quite breezy, especially over northern Iowa later this
morning through the afternoon with gusts upwards of 35-40 mph. 

Tonight and beyond: 

Winds relax into the evening, though temperatures falling near to 
just below freezing across the state will likely allow for additional 
frost/freeze headlines into Saturday morning. 

Continued dry weather is expected through the weekend, with
temperatures gradually warming into the upper 50s to low 60s by
Sunday. Before that though, can expect one more chilly night with
more expected frost/freezing conditions Saturday night into Sunday
morning. Expect slightly breezy conditions this weekend with partly
cloudy skies Saturday and clearing skies Sunday. Changes arrive into
the start of the work week as the chance for showers and storms
returns, along with continued warming through the 60s.
